If we divide 12.6/4.5 by 3 we receive 4.2/1.5. So yes they are proportional. <span />
Answer:
7y + 14
Step-by-step explanation:
7(y+2) = 7y + 14
Answer:
<BCO = <BAO = 20degrees
Step-by-step explanation:
If <ABC measures 100 and is inscribed in a circle O. find <BAO and <BCO
To get <BAO and <BCO, we need to get <AOC first.
From the figure, it can be seen that triangle ABC is an isosceles trinagle. Hence;
<BAC + <BCA + 100 = 180
Since <BAC = <BCA
<BAC + <BAC = 180 - 100
2<BAC = 80
<BAC = 80/2
<BAC = 40
Also;
<BAO = <BCO and <BAO = <BAC/2
<BAO = 40/2 = <BCO
Hence <BCO = <BAO = 20degrees
Answer:
55
Step-by-step explanation:
sinx = opposite/hypotenuse = 9/11
x = arcsin(9/11) = 54.9031987, which is about 55, degrees
